Under quite general conditions, the biological response j(G) to a very weak continuous 60-Hz electric or magnetic field G is shown to be proportional to the square of the field strength. This conclusion follows from the continuity of the function j(G) and the first three derivatives of j(G) with respect to G over the amplitude of G. That continuity is ensured in nominally discontinuous systems by the presence of thermal noise. I argue the validity of the conjecture that all plausible biological responses to weak 60-Hz fields vary with the square of the field strength. A specific model is used to illustrate characteristic dependencies of biological responses to exposure times.
在相当一般的条件下，已证明生物对非常微弱的连续60赫兹电场或磁场G的响应j(G)与场强的平方成正比。这一结论源于函数j(G)及其关于G的前三阶导数在G的振幅范围内的连续性。在名义上不连续的系统中，热噪声的存在确保了这种连续性。我论证了这样一个猜想的有效性，即所有对微弱60赫兹场的合理生物响应都随场强的平方而变化。使用一个特定模型来说明生物响应与暴露时间的特征依赖性。
